DISTINGUISHING DIFFERENT STYLES OF TRANSPRESSIONAL DEFORMATION AT AN OBLIQUELY CONVERGENT PLATE MARGIN, FIORDLAND, NEW ZEALAND A Thesis Presented by Emily Sarah Lincoln to The Faculty of the Graduate College of The University of Vermont In Partial Fulfillment of the Requirements for the Degree of Master of Science Specializing in Geology August, 2021 Defense Date: May 25, 2021 Thesis Examination Committee: Keith A. Klepeis, Ph.D., Advisor Kristen Underwood, Ph.D., Chairperson Laura Webb, Ph.D. Cynthia J. Forehand, Ph.D., Dean of the Graduate College ABSTRACT Fiordland, New Zealand provides one of the best-known and deepest (to 65 km) exposures of an Early Cretaceous magmatic arc root known to geologists. These exposures allow for us to study tectonic deformational processes at varying crustal depths, including the role of pre-existing structures on later reactivation. The well- preserved Grebe shear zone (GSZ) marks the boundary between major basement terranes in southern Fiordland and has undergone multiple episodes of deformation during the Cretaceous and Cenozoic time periods. The primary focus of this study is to recognize and characterize the differing phases of deformation that occurred along this shear zone. To investigate these phases, we have conducted structural, finite strain, fault-slip, and kinematic analysis, on structural measurements and samples taken from Fiordland. We use these methods in concert to identify and differentiate the deformational styles. In southern Fiordland, the GSZ is characterized by a narrow zone of protomylonitic-mylonitic fabric within amphibolite retrogressed to greenschist facies rock. Finite strain analysis on feldspar aggregates from samples in and around the GSZ produced primarily oblate ellipsoids, indicative of shortening across the shear zone. Asymmetrical shear sense indicators present in thin sections oriented parallel, perpendicular, and oblique to lineations also suggest a component of sinistral obliquity in shear zone fabrics. This coupled with a deflection of foliations in surrounding rock towards parallelism with the shear zone boundary is consistent with transpressional deformation. This deformation is localized to a zone of ductile deformation where components of sinistral strike-slip and shortening are accommodated in close proximity to the shear zone (non-partitioned). This deformational event is associated with the formation of the shear zone and is overprinted by a separate transpressional event that took place during the Cenozoic. Fault-slip analysis showed that this reactivation event is accommodated in primarily brittle faults in where one set accommodates mostly or purely strike-slip motion, and another that accommodates mostly or purely reverse motion (partitioned). This contrasting style of transpression implies that the Cretaceous ductile shear zone influenced the behavior of strain during Cenozoic reactivation. ACKNOWLEDGEMENTS I have many people to thank for the completion of this thesis, the first being my advisor Keith Klepeis, for being a tremendous source of knowledge and support. Not only is he extremely knowledgeable and passionate about the subject, but he also genuinely cares about the success of his students. I could not have asked for a better mentor during my time in the program. I would also like to thank Laura Webb and for her support and help with the microstructure portion of my analysis, and Kristen Underwood for generously agreeing to be my chairperson in short notice. Within the UVM Geology Department, I would also like to thank John Hughes for his words of encouragement, which helped me immensely through both the program and the COVID- 19 pandemic. This project would not be possible without our collaborators, and I greatly thank Elena Miranda and Joshua Schwartz from CSUN, and Rose Turnbull and Richard Jongens from the New Zealand GNS for sharing their seemingly infinite knowledge both in the field and after. Lastly, I would like to thank my spouse, Stephen, for pushing me to pursue this in the first place, and for his help along the way. ii TABLE OF CONTENTS ACKNOWLEDGEMENTS ............................................................................................. ii LIST OF TABLES .......................................................................................................... vi LIST OF FIGURES ....................................................................................................... vii CHAPTER 1: INTRODUCTION .................................................................................... 1 CHAPTER 2: LITERATURE REVIEW ......................................................................... 6 2.1 Shear Zone Anatomy ............................................................................................. 6 2.1.1.

  • FIORDLAND NATIONAL PARK 287 ( P311 ) © Lonely Planet Publications Planet Lonely ©
    © Lonely Planet Publications 287 Fiordland National Park Fiordland National Park, the largest slice of the Te Wahipounamu-Southwest New Zealand World Heritage Area, is one of New Zealand’s finest outdoor treasures. At 12,523 sq km, Fiordland is the country’s largest park, and one of the largest in the world. It stretches from Martins Bay in the north to Te Waewae Bay in the south, and is bordered by the Tasman Sea on one side and a series of deep lakes on the other. In between are rugged ranges with sharp granite peaks and narrow valleys, 14 of New Zealand’s most beautiful fiords, and the country’s best collection of waterfalls. The rugged terrain, rainforest-like bush and abundant water have kept progress and people out of much of the park. Fiordland’s fringes are easily visited, but most of the park is impenetrable to all but the hardiest trampers, making it a true wilderness in every sense. The most intimate way to experience Fiordland is on foot. There are more than 500km of tracks, and more than 60 huts scattered along them. The most famous track in New Zealand is the Milford Track. Often labelled the ‘finest walk in the world’, the Milford is almost a pilgrimage to many Kiwis. Right from the beginning the Milford has been a highly regulated and commercial venture, and this has deterred some trampers. However, despite the high costs and the abundance of buildings on the manicured track, it’s still a wonderfully scenic tramp. There are many other tracks in Fiordland.

We compare 20 U-Pb zircon ages from >2300 km2 of Mesozoic lower and middle crust of the Western Fiordland Orthogneiss to existing data from the Median Batholith to: (1) document the tempo of arc construction, (2) estimate rates of magmatic addition at various depths during arc construction, and (3) evaluate the role of cyclical feedbacks between magmatism and deformation during high and low magma addition rate events. Results from the Western Fiordland Orthogneiss indicate that the oldest dates are distributed in northern and southern extremities: the Worsley Pluton (123–121 Ma), eastern McKerr Intrusives (128–120 Ma), and Breaksea Orthogneiss (123 Ma). Dates within the interior of the Western Fiordland Orthogneiss (Misty and Malaspina Plutons, western McKerr Intrusives) primarily range from 118 to 115 Ma and signify a major flux of mafic to interme- diate magmatism during which nearly 70% of the arc root was emplaced during a brief, ~3 m.y., interval.

Gaymer, Vreni Häussermann, and Jake Rice (Co-Lead member and Editor Part VI Biodiversity) 1. Introduction The Pacific Ocean is the Earth’s largest ocean, covering one-third of the world’s surface. This huge expanse of ocean supports the most extensive and diverse coral reefs in the world (Burke et al., 2011), the largest commercial fishery (FAO, 2014), the most and deepest oceanic trenches (General Bathymetric Chart of the Oceans, available at www.gebco.net), the largest upwelling system (Spalding et al., 2012), the healthiest and, in some cases, largest remaining populations of many globally rare and threatened species, including marine mammals, seabirds and marine reptiles (Tittensor et al., 2010). The South Pacific Ocean surrounds and is bordered by 23 countries and territories (for the purpose of this chapter, countries west of Papua New Guinea are not considered to be part of the South Pacific), which range in size from small atolls (e.g., Nauru) to continents (South America, Australia). Associated populations of each of the countries and territories range from less than 10,000 (Tokelau, Nauru, Tuvalu) to nearly 30.5 million (Peru; Population Estimates and Projections, World Bank Group, accessed at http://data.worldbank.org/data-catalog/population-projection-tables, August 2014). Most of the tropical and sub-tropical western and central South Pacific Ocean is contained within exclusive economic zones (EEZs), whereas vast expanses of temperate waters are associated with high seas areas (Figure 1).
